The present invention generally concerns the field of musical wind instruments with a single flapping reed, and relates more particularly to the technical field of the fastening devices of a single flapping reed to the mouthpiece of a musical instrument, for example a clarinet or a saxophone.
The present invention concerns more particularly a ligature for attaching a single flapping reed to a mouthpiece of a musical instrument, said ligature comprising a main body intended to be secured to said mouthpiece.
The present invention also concerns an attachment method of a single flapping reed to a mouthpiece of a musical instrument by means of a ligature, said ligature comprising a main body intended to be secured to said mouthpiece.
The sound of musical wind instruments with a single flapping reed, such as for example the clarinet or the saxophone, is produced by the vibration of a reed on a mouthpiece under the effect of the breath of the musician taking the mouthpiece between his lips. Made from a part of cane, metal or plastics, a single flapping reed is constituted, starting from its distal end to its proximal end, of a heel and a table, said table constituting the vibratile portion of the reed. At its most proximal end, the table has an extremely thin thickness, so that it is particularly sensitive to the alteration and clogging due in particular to the contact with the mouthpiece or the handling during the setting-up and the setting of the reed.
The mouthpiece is, in turn, mainly composed of three functional areas, namely a table, a beak and a pipe. The table, or receiving surface of the reed, consists in the association of a flat surface, receiving the heel or a fixed portion of the reed, and a curved surface, drawing the opening of the mouthpiece. Extending in a coplanar manner with the flat face of the table of the mouthpiece, the beak is the surface on which the reed is fastened to the mouthpiece. Finally, the pipe is the meeting of the bore, which extends towards the body of the instrument, and the chamber which extends, in turn, towards the mouth of the musician and which comes out from the mouthpiece under the table of the reed.
The relative position of the reed on the mouthpiece of a musical wind instrument, for example of the clarinet or saxophone type, may greatly influence the sound and the play features of the instrument. Consequently, a very high accuracy of the positioning of the reed on the mouthpiece is sought by the musician. Conventionally, the reed is held in position on the mouthpiece, at the beak, using a member called ligature, a kind of ring or collar which secures the heel of the reed to the mouthpiece while authorizing the vibration of the table of the reed. Such a ligature may be flexible, for example made of leather, or on the contrary substantially rigid, for example made of metal or plastics.
According to this well-known solution, the musician positions the reed on the mouthpiece of his instrument, then comes to clasp it with a ligature. This results in an iterative setting of the respective positions of the reed and the ligature, relative to each other and to the mouthpiece, until obtaining a positioning of the reed allowing obtaining the desired optimal sound result. This procedure of fastening and setting may prove to be relatively laborious, impractical and not very accurate, because the ligature should be systematically adjusted again each time the reed is displaced. In particular, the fine settings of the reed relative to the mouthpiece tip are in particular difficult. Thus, this results in a loss of time, a risk of damage to the table of the reed, for an uncertain result. This issue is stronger as far as it is about beginner musicians or student musicians. Indeed, it is not uncommon for the teacher to devote a part of his teaching time to helping his students to adequately fasten the reed on their instruments.
Solutions have been regularly sought to remedy these drawbacks, but unfortunately, they remain very often very complex to implement, unergonomic in particular for beginner musicians with the limited dexterity, and sometimes even require prior specific preparation of the reed, for example at its heel, or else the use of a reed expressly developed for a use with the corresponding ligature.
The invention consequently aims to remedy the different drawbacks previously listed, and to propose a new ligature which, while being in particular simple, practical and ergonomic for use, allows an optimal holding of the reed on the mouthpiece.
Another object of the invention aims to propose a new ligature allowing proceeding to the replacement of a reed in a particularly simple and fast manner.
Another object of the invention aims to propose a new ligature allowing locking/unlocking the reed in position relative to the mouthpiece in a particularly ergonomic manner only requiring the use of a single hand.
Another object of the invention aims to propose a new ligature further allowing a particularly easy, fast and accurate manual setting of the positioning of the reed relative to the mouthpiece of the instrument.
Another object of the invention aims to propose a new ligature which, while allowing a particularly easy, fast and accurate manual setting of the positioning of the reed relative to the mouthpiece of the instrument, may be used with a standard reed, without requiring transforming or adapting the body of the reed.
Another object of the invention aims to propose a new fastening device of a reed on the mouthpiece of the instrument of a musical wind instrument with single flapping reed designed to significantly limit the risk of damaging the reed, in particular by a friction thereof during its setting-up or the setting of the position thereof.
Another object of the invention aims to propose a new attachment method of a single flapping reed to a mouthpiece of a musical instrument, in particular simple, practical and fast to implement, which only requires a minimum number of manual operations.
Another object of the invention finally aims to propose a new attachment method of a single flapping reed to a mouthpiece of a musical instrument allowing a particularly easy, fast and accurate manual setting of the positioning of the reed relative to the mouthpiece of the instrument.
The objects assigned to the invention are reached using an attachment ligature of a single flapping reed to a mouthpiece of a musical instrument, said ligature comprising a main body intended to be secured to said mouthpiece and being characterized in that it further comprises:
and an elastic return member, which elastically returns said holding member and control lever respectively in the stress position and in the rest position.
The objects assigned to the invention are also reached using an attachment method of a single flapping reed to a mouthpiece of a musical instrument by means of a ligature, said ligature comprising a main body intended to be secured to said mouthpiece, said method being characterized in that said mouthpiece also comprises a holding member of the reed, movably mounted relative to said main body between a stress position, which is an elastic return position in which the holding member is designed to exert on the reed an immobilization stress of the reed relative to the mouthpiece and at least one release position in which the holding member is designed to release said stress in order to authorize a displacement of the reed relative to the mouthpiece, said method comprising the following steps, in chronological order:
Other objects and advantages of the invention will appear in more detail upon reading the description which follows, as well as using the appended drawings provided for purely explanatory and non-limiting purposes, in which:
Moreover, the reed 3 shown alone in
According to the invention, the ligature 1 comprises a main body 13 intended to be secured to the mouthpiece 2 of the instrument. The term «secured means» that the main body 13 is firmly fastened to the mouthpiece 2, on at least one portion of its length, such that it cannot be displaced relative to the mouthpiece 2 once positioned and fastened on said mouthpiece, either by an intentional or unintentional handling of the musician, or simply by the vibrations of the body of the instrument. Preferably, the main body 13 is removably secured to said mouthpiece 2 of the instrument, such that for example the same ligature 1 may be used with different mouthpieces. Alternatively, it is quite possible, without departing from the invention, that the main body 13 is non-removably secured to the mouthpiece 2, that is to say that the main body 13 is permanently fastened to said mouthpiece 2. In order to allow this securing of the main body 13 to the mouthpiece 2 of the instrument, said main body 13 preferably comprises a collar 14 intended to encircle the mouthpiece 2, for example at the beak 8 of said mouthpiece 2, said collar 14 is provided with an attachment member 15 allowing the removable fastening of the collar 14 to the mouthpiece 2.
According to a preferred embodiment of the invention, and as shown in
Said attachment member 15 comprises at least one clamping screw (not shown) provided with a manually actuatable clamping/unclamping head, for example of the thumbwheel type. In the preferred embodiment illustrated in the figures, this clamping screw advantageously constitutes a complementary means allowing bringing the jaws 16 closer to the collar 14 by screwing/unscrewing. However, it is possible, of course, to imagine an alternative configuration of said fastening member 15, according to which said fastening member 15 would comprise at least one screw, said screw not being a clamping screw, but for example, a set screw.
According to an important feature of the invention, the ligature 1 further comprises a holding member 17 of the reed 3, movably mounted relative to said main body 13, preferably pivotally along a first pivot axis A-A′, between a stress position in which the holding member 17 is designed to exert on the reed 3, for example on the upper face 4 at the heel 9 of said reed 3, an immobilization stress of the reed 3 relative to the mouthpiece 2 and at least one release position in which the holding member 17 is designed to release said stress in order to authorize a displacement of the reed 3 relative to the mouthpiece 2. As particularly shown in
The holding member 17 is, further, preferably constituted of a deformable material in compression, both capable of absorbing, at least partially, the possible vibrations of the heel 9 of the reed 3 and of opposing the displacement of the reed 3 relative to the mouthpiece 2, by the single friction force of the holding member surface 17 on the surface 4 of the heel 9 of the reed 3 when said holding member 17 is in the stress position. Suitable materials for producing such a holding member 17 are, for example and without limitation, felt, rubber or more generally a material of the family of elastomers. Preferably, the holding member 17 is distinct and independent of the attachment member 15 previously described. It is thus advantageously possible for the user to act on the fastening and the positioning of the reed 3 relative to the mouthpiece 2 without accidentally modifying the positioning of the ligature 1 itself relative to said mouthpiece 2, and without having to dissociate or unclamp the ligature 1 of the mouthpiece 2.
According to the invention, the ligature 1 further comprises a control lever 18 manually actuatable and pivotally mounted relative to the main body 13, preferably along a second pivot axis B-B′, between a rest position in which said lever 18 cooperates with the holding member 17 so that said holding member occupies the stress position thereof and at least one actuated position in which said lever 18 stresses the holding member 17 in the release position thereof.
Preferably, said ligature being designed so that, when the main body 13 is secured to the mouthpiece 2, said second pivot axis B-B′ extends in a transverse direction substantially perpendicular to the longitudinal direction in which the bore mean central axis X-X′ extends.
Preferably, the first pivot axis A-A′ of the holding member 17 relative to the main body 13, and the second pivot axis B-B′ of the control lever 18 relative to the main body 13 coincide.
As illustrated in particular in
The ligature 1 is preferably designed so that, when the main body 13 is secured to the mouthpiece 2, said lower portion 21 is farther from the bore mean central axis X-X′ in the rest position than in the actuated position, the control lever 18 being designed to switch from the rest position thereof to the actuated position thereof in response to a pressure exerted on said lower portion 21, preferably forming said handle 22, in the direction of said bore mean central axis X-X′. Preferably, and as illustrated in the figures, said control lever 18 protrudes from said main body 13, towards the bottom of the instrument when it is handled by the user in the playing position. This spatial configuration of the lever 18 also contributes to make the use of said ligature 1 particularly practical, the user being capable, with the same hand, of holding the body of the instrument and of interacting with the control lever 18. Advantageously, said portion upper 20 of the control lever 18 carries said holding member 17, preferably at its free end. In other words, the holding member 17 is advantageously mechanically connected to the upper portion 20 of the control lever 18.
In the preferred embodiment shown in the figures, said holding member 17 is secured by one of the faces thereof to the end of said upper portion 20 of the control lever 18, the opposite face of the holding member 17 being, in turn, intended to be opposite to the reed 3, such that the holding member 17 and the control lever 18 are part of one and the same unit part.
Still according to an important feature of the invention, the ligature 1 further comprises an elastic return member 23, which elastically returns, by design, said holding member 17 and control lever 18 respectively in the stress position and in the rest position. In other words, the elastic return member 23 is designed to elastically return said holding member 17 and control lever 18 respectively to the stress position and to the rest position. Advantageously, and as illustrated in particular in
Preferably, the ligature 1 comprises a lateral guide device 25 secured to the main body 13 and designed to hold the reed 3 aligned with the mouthpiece 2 while authorizing a longitudinal sliding of the reed 3 along the mouthpiece 2 when the holding member 17 occupies the release position thereof. As illustrated in
As illustrated in
In a particularly advantageous manner, the ligature 1 comprises a setting device 27 designed to adjust, in response to a control handling of a user, the longitudinal positioning of the reed 3 relative to the mouthpiece 2, preferably once the reed 3 placed within the lateral guide device 25. This device is preferably distinct from the fastening system, formed by the collar 14 and the attachment member 15, of the ligature 1 on the mouthpiece 2 of the instrument. This has the major advantage, unlike many existing ligature solutions, of allowing the user to set the longitudinal positioning of the reed 3 relative to the mouthpiece 2 independently not only of the relative positioning of the ligature 1 relative to said mouthpiece 2, but also independently of the lateral positioning of the reed 3, which stresses it by the lateral guide device 25 secured to the main body 13.
As illustrated in
According to the embodiment illustrated in particular in
According to another embodiment, illustrated in particular in
In addition, said setting device 27 preferably comprises a carriage guide 35, relative to which said movable carriage 28 is slidably mounted. Advantageously housed between the cheeks 26 of the lateral guide device 25, said carriage guide 35 is itself movably mounted relative to said main body 13. According to a preferred embodiment of the invention illustrated in particular in
Said carriage guide 35 is advantageously mechanically connected to said control lever 18 so that the displacement of said carriage guide 35 is controlled by the manual actuation of said lever 18. In other words, said carriage guide 35 is advantageously movably mounted relative to the main body 13, is mechanically connected to said control lever 18 and is configured so that the displacement of said carriage guide 35 is controlled by the manual actuation of said lever 18. Said carriage guide 35 is thus advantageously designed to fulfill a dual technical function. Indeed, it allows, in a first function, to stress the longitudinal displacement of the carriage 28 relative to the mouthpiece 2. The movable carriage 28, slidably mounted relative to the carriage guide 35, may indeed move only between a position Pmin, in which said carriage 28 abuts against the distal wall 38 of the carriage guide 35, and a position Pmax, in which said carriage 28 abuts this time against the proximal wall 39 of the carriage guide 35.
In a particularly preferred manner, the maximum travel of the carriage 28 between the positions Pmin and Pmax thereof is substantially equal to 4 mm, which allows providing the user with an optimum setting range of the longitudinal position of the reed 3 relative to the mouthpiece 2 of the instrument.
Still according to a particularly advantageous embodiment illustrated in
In a particularly advantageous manner, a first leg 45 of said at least one torsion spring 24 preferably constituting the elastic return member 23 bears under the lower portion 21 of the control lever 18, while its second leg 46 bears in the groove of at least one, preferably two, corresponding longitudinal slots 47 formed in the upper surface 48 of the carriage 28. This configuration is particularly seen in
The cooperation between the carriage 28, the carriage guide 35, the control lever 18 and the main body 13 is thus configured only when the handle 22 of the control lever 18 is actuated and that said control lever pivots relative to the main body 13 of the rest position thereof to at least one actuated position, the arms 43 are capable of causing in the movement thereof, similar to the movement of a balance, a longitudinal displacement of the carriage guide 35 relative to the mouthpiece 2, towards the opening of the mouthpiece 2.
Each of the cheeks 26 of the guide device 25, as described above and illustrated in
However, the effort exerted on the carriage 28 by said second corresponding leg 46 of the at least one torsion spring 24, holds said carriage 28 in permanent contact with the carriage guide 35 and opposes, because of the single friction force of said second leg 46 in the groove of the at least one longitudinal slot 47 of the carriage 28, to the longitudinal displacement of the carriage 28 relative to the mouthpiece 2 induced by the path of the carriage guide 35. Consequently, while the carriage guide 35 describes, under the effect of the actuation of the handle 22 of the control lever 18, a curvilinear trajectory, the carriage 28 is, in turn, substantially displaced only in an orthogonal translational movement relative to the bore mean central axis X-X′ of the mouthpiece 2. In this manner, the carriage 28 is preferably mechanically connected to the control lever 18 and the ligature 1 is advantageously designed such that when the main body 13 is secured to the mouthpiece 2, the switch of the control lever 18 from its rest position to its activated position causes a spacing of the carriage 28 relative to the bore mean central axis X-X′. In a particularly advantageous manner, the maximum spacing accordingly generated between the reed 3, housed in the carriage 28, and the table 7 of the mouthpiece 2 of the instrument to which the main body 13 of the ligature 1 is secured is substantially equal to 1 mm. This relative spacing, induced by the actuation of the handle 22 of the control lever 18, of the carriage 28 relative to the mouthpiece 2 of the instrument to which the ligature 1 is secured, allows the user, on the one hand, to easily insert the reed 3 into the lower housing 29 of the carriage 28, and, on the other hand, once said reed 3 housed in said lower housing 29, to set the longitudinal positioning of the reed 3 relative to the mouthpiece 2 through the actuation of the setting device 27 without generating a potentially harmful friction of said reed 3 on said mouthpiece 2.
Alternatively, the setting device 27 may comprise a carriage 28 which is, on the contrary, not mechanically connected to the control lever 18, such that the switch of said control lever from its rest position to its activated position does not cause in this case a spacing of the carriage 28 relative to the bore mean central axis X-X′. It will be understood that, in this embodiment, the ligature 1 then preferably does not comprise a carriage guide 35, and the cheeks 26 of the guide device 25 are preferably devoid of ramps.
Advantageously, the holding member 17 is designed to degrade the operation of said setting device 27 when it occupies the stress position thereof, and on the contrary to promote the operation of said setting device 27 when it occupies the release position thereof. The term «degrade» means that the holding member 17 partially, and not completely, opposes the proper operation of said setting device 27. Indeed, if the holding member 17 is designed to degrade the operation of said setting device 27 when it occupies the stress position thereof, for example by the single friction force exerted by the holding member 17 on the reed 3, however, preferably it does not completely inhibit the operation of said setting device 27, such that it is still nevertheless possible for the user to maneuver the setting device 27 even though the holding member 17 occupies the stress position thereof in which said holding member 17 presses on the reed 3 and plate it on the table 7 of the mouthpiece 2. For this purpose, it is sufficient for the user to exert on the setting device 27 a sufficient force to counter the friction force of the upper surface of the holding member 17 on the upper surface of the heel 9 of the reed 3. Consequently, this advantageously allows the user to carry out a particularly fine setting of the longitudinal position of the reed 3 relative to the mouthpiece 2. Conversely, when the holding member 17 occupies the release position thereof, it is advantageously no longer in contact with the reed 3 and, consequently, promotes the operation of the setting device 27. It is of course possible, without departing from the scope of the invention, to consider other means allowing the holding member 17 to degrade, without completely prohibiting, or to promote the operation of the setting device 27. It may for example be considered that the holding member 17 is provided with a cam or a finger which would interfere with the setting device 27 by friction so as to hinder its proper operation, when the holding member 17 occupies the stress position thereof.
Preferably, the setting device 27 comprises a manually actuatable control member 50. This control member 50 is advantageously distinct from the control lever 18, so as to allow a simultaneous handling, in particular practical, of both, a hand of the user acting on the lever 18, while the other hand acts on the control member 50 of the setting device 27. Still more preferably, this control member 50 comprises both a rotary setting thumbwheel 51, and a transformation system 52 of the rotational movement of said thumbwheel 51 into a longitudinal sliding movement of the reed 3 along the mouthpiece 2.
Said movement transformation system 52 preferably comprises a gear sector 53, for example, according to the embodiment shown in particular in
According to a preferred embodiment of the invention, and as illustrated in
Furthermore, the movable carriage 28 has, according to the preferred embodiment illustrated in the figures, a shaped portion forming a rack 58 in contact with the gear wheel 54, said rack 58 being advantageously integral with the carriage 28 so as to form with said carriage a single one-piece part.
The setting device 27 preferably comprises a transmission system 59, mounted between the control member 50 and the transformation member 52 and designed to move between:
According to the preferred embodiment shown in the figures, said transmission system 59 coincides with the assembly formed by the thumbwheel 51 of the control member 50 and the rod 55 of the transformation system 52.
Preferably, the control member 50 moreover comprises a manual activation member 60 of the transmission system 59, in order to allow the switch of said transmission system 59 from its inhibition configuration to its activation configuration. Thus, the transmission system 59 is preferably inhibited when the activation member 60 is not maneuvered, which allows avoiding any unintentional modification by the musician of the setting of the positioning of the reed 3.
According to a first particularly advantageous embodiment, and as illustrated in
When maneuvering the activation member 60, the rod 55 meshes with the gear wheel 54 (
Furthermore, according to this first embodiment, the activation member 60 may also include a second elastic return member 63, for example a compression spring 64, mounted between the thumbwheel 51 and the main body 13, distinct from the elastic return member 23 of the holding member 17 and the control lever 18, and intended to elastically return the transmission system 59 in the inhibition configuration thereof when the activation member 60 is not maneuvered.
According to the preferred embodiment illustrated in particular in
According to a second embodiment, illustrated in
In this second embodiment, the gear wheel 54 is advantageously mounted in a simple translation relative to the rod 55 so as to be capable of sliding axially about the rod 55, for example thanks to a similar key/spline system (
When the second key 66 of the gear wheel 54 cooperates with the second spline 67 formed in the periphery of the through-orifice of the first lug 56, the activation member 60 holds the transmission system 59 in the inhibition configuration thereof, in which it then prohibits any rotational movement of the thumbwheel 51. On the contrary, when the gear wheel 54 is disengaged from the first lug 56, by sliding along the rod 55, and the second key 66 of the gear wheel 54 no longer cooperates with the second spline 67, the activation member 60 allows the transmission system 59 to occupy the activation configuration thereof, in which it then authorizes the rotational movement of the thumbwheel 51 and the transmission of this movement.
As in the previous embodiment, the activation member 60 may also advantageously include a second elastic return member 63′, preferably mounted between the thumbwheel 51 and the main body 13, intended to elastically return the transmission system 59 to the inhibition configuration thereof when the activation member 60 is not maneuvered.
However, in a particularly advantageous manner and as illustrated in
Thus, the actuation of the activation member 60 is consequently obtained by exerting a pressure on the setting thumbwheel 51, according to the axis of rotation of said thumbwheel 51 which coincides with the first pivot axis A-A′, so as to counter the effort of the spring 24′ and to disengage the gear wheel 54 from the first lug 56 of the body 13 by sliding it along the rod 55. The implementation of such a unique spring 24′ thus advantageously allows simplifying the design and the manufacture of the ligature 1, while ensuring a better management of the associated costs.
For the sake of managing costs, ease of manufacture and lightness, and more particularly in a variant of the ligature 1 intended for student musicians and amateur musicians, all or part of the elements constituting the ligature 1 may be made of plastics, since said ligature has a rigidity and a robustness sufficient to allow said elements to properly perform their functions.
It is, however, perfectly possible to consider, in a variant on the contrary intended for experienced musicians and professionals, looking for a ligature combining the features according to the invention, robustness and aesthetics, that all or part of the elements constituting the ligature 1 is manufactured of metal or metal alloy, for example aluminum or titanium, in order to provide them with a better mechanical strength over time. The visible parts, such as for example the control lever 18, the main body 13 and the thumbwheel 51, may also be gilded with fine gold in order to provide them with a refined appearance.
The invention also concerns an attachment method of a single flapping reed 3 to a mouthpiece 2 of a musical instrument by means of a ligature 1, said ligature 1 comprising a main body 13 intended to be secured to said mouthpiece 2, said method being characterized in that said ligature 1 also comprises a holding member 17 of the reed 3, movably mounted relative to said main body 13 between a stress position, which is an elastic return position in which the holding member 17 is designed to exert on the reed 3 an immobilization stress of the reed 3 relative to the mouthpiece 2 and at least one release position in which the holding member 17 is designed to release said stress in order to authorize a displacement of the reed 3 relative to the mouthpiece 2, said method comprising the following steps, in chronological order:
According to the preferred embodiment shown in the figures, the main body 13 of the ligature 1 is secured to the mouthpiece 2 by the user, the control lever 18 protruding to the bottom of the instrument when said instrument is handled by the user in the playing position, and held firmly fastened thereto via the clamping screw (not shown) of the attachment member 15 of the collar 14.
Using a free finger of the hand holding the instrument, for example with the thumb, the user advantageously presses on the handle 22 in order to actuate the control lever 18, so as to pivot it from its rest position to its actuated position in which said control lever 18 stresses the holding member 17 in the release position and to allow access of the reed 3 to the carriage 28.
The holding member 17 being stressed in the release position, the user, using his free hand, carefully inserts the reed 3 by force between the mouthpiece 2 and the holding member 17, advantageously in the lower housing 29 of the carriage 28, by sliding the edges 5 of the heel 9 of the reed 3 on the spuds 34 and along the lateral edges 31 of the carriage 28, until the distal end of the heel 9 of the reed 3 abuts against the distal end 32 of the carriage 28.
Once the reed 3 firmly positioned within the lower housing 29 of the carriage 28, the user gradually ceases his effort on the handle 22 of the control lever 18, which has the effect of simultaneously causing the return of the control lever 18 towards the rest position thereof, bringing the carriage guide 35 and the carriage 28 closer to the bore mean central axis X-X′ until the lower flat face 6 of the heel 9 of the reed 3 comes into contact with the table 7 of the mouthpiece 2, and the return of the holding member 17 to the stress position.
The implementation method of the ligature 1 further comprises, and in a particularly advantageous manner, a step (v) of adjusting the longitudinal positioning of the reed 3 including the following operations, in chronological order:
Preferably, the manual actuation operation of the setting device 27 of the longitudinal positioning of the reed 3 comprises the following sub-operations:
According to the preferred embodiment illustrated in the figures, and in particular in
And, once the optimal setting is obtained:
It should be noted that, without departing from the scope of the invention, the implementation method of the ligature 1 may comprise the implementation of some of the operations in which the control lever 18 would not be fully actuated, that is to say that the pressure exerted on the handle 22 which preferably forms the lower portion 21 of the lever 18 is not sufficient to bring said handle 22 into contact with the main body 13, or in which the actuation thereof would not be fully ceased, that is to say that the effort exerted on said handle 22 is not fully ceased such that the reed 3 is not perfectly pressed against the table 7 of the mouthpiece 2.
Such an intermediate use of control lever 18 advantageously provides the user with a possibility of particularly fine and accurate setting of the positioning of the reed 3 relative to the mouthpiece 2, by taking advantage of the friction forces being exerted between the upper face 4 of the heel 9 of the reed 3 and the surface of the holding member 17 placed opposite thereto.
The invention finds the industrial application thereof in the design, the manufacture and the use of ligatures for musical wind instruments.
